CIRCULATING PUMP.

Application fi1ed. October 20, 1926. Serial No. 142,891.

This invention relates to circulating pumps. for automobiles.

In certain types of automobiles, it is the practice to provide a transverse supporting plate for the front end of the motor. This plate is apertured to permit the passage therethrough of the lower connection for the radiator. The consequence of this construction is that it has been considered practically an impossibility to provide a circulating pump at the lower portion of the radiator for this type of internal combus-- tion engine.

This invention is designed to provide a circulating pump which is so constructed that it will readily accommodate the front supporting member of an internal combustion engine, and so made that it will utilize the aperture regularly found in this front supporting member, so that the pump'may be clamped in place through this aperture without requiring additional holes to be drilled in the supporting member.

Further objects of this invention are to provide a circulating pump which may be made in a practical and cheap manner by ordinary machine shop practices, and which will yet accommodate itself to the above described type of motor construction.

An embodiment of the invention is shown in the accompanying drawings in which Figure 1 is a fragmentary front view of an internal combustion automobile engine with the pump in place, such view being partly broken away;

Figure 2 is a side View partly in section of the structure shown in Figure 1.

Referring to the drawings, it will be seen that the pump comprises a main body portion 1 from which a downwardly extending delivery pipe 2 projects. This pipe extends downwardly and terminates in an upwardly slanting outlet portion 3 adapted to be attached to the pipe 4 leading to the engine block. The inlet portion of the pump is indicated by the reference character 5, and is provided with a downwardly extending suction pipe or portion 6 which terminates in the inlet portion 7 in line with the portion 3 and ada ited to be connected to the lower pipe 8 0 the radiator 9.

The main members 1 and 5 0f the pump are securely fastened together by means of screws 10 which pass through the flange 11 on the front side of the supporting member 12 of the engine. Further, it will be noted from Figure 1, that the bar 15 has an upwardly extending portion 16 which has a threaded upper aperture, as indicated at 17 to receive the uppermost of the bolts 14.

The pump may be driven by the fan belt 18, as shown in Figure 1, it being noted that the pulley 19 of the pump is mounted sufliciently far away from the pulley 20 of the fan and the driving pulley 21 to provide the necessary length of belt to secure an effective drive.

It will be seen that a novel form of circulating pump has been provided by this invention which will accommodate the front supporting plate of an automobile engine, and which may be bolted through the ordinary opening 22 regularly found in these front plates without requiring any additional holes to be drilled in the front plate.

Further, it will be seen that the pump is of a very compact design and maybe simply constructed as well as readily bolted in place.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

1. The combination of an internal combustion engine having a transverse front Supporting plate, a circulating pump mounted above said plate and having a spaced inlet and outlet portion adapted to straddle said plate and extending downwardly on opposite sides of said plate, and means for clamping said pump to said plate.

2. The combination of an internal combustion 7 engine having a transverse front supporting plate provided with an apersaid circulating pipe on opposite sides of said plate, a bar mounted transversely of said aperture, and a plurality of bolts passing through lugs carried by one of said downwardly extending portions and threaded into said bar to clamp said pump to said plate, certain of said bolts passing through said aperture. 7

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in

the county 01": Milwaukee and State of Wis- 25 V consin.
